  • Description

Naspm 3Hcl(1-Naphthylacetyl spermine) is a potent and selective Ca2+ permeable AMPA receptor(Ca-perm AMPAR) blocker.
IC50 value:
Target: CP-AMPAR blocker
Naspm is a selective blocker of Ca(2+)-permeable GluA2-lacking AMPA receptors, reduced MNNG-induced CA1 pyramidal cell death [1]. intra-ACC injections of the CP-AMPAR channel antagonist, 1-naphthylacetyl spermine (NASPM) immediately following trace fear conditioning blocked 24 h fear memory retrieval [2]. TNF-α+PDC caused considerable MN degeneration was blocked by the Ca-perm AMPAr selective blocker, 1-naphthyl acetylspermine (NASPM) [3]. Blockage of CP-AMPARs with Naspm (100μM) results in most cases in a significant reduction of the PPD magnitude, also reversing to paired-pulse facilitation in some cases [4].
